Melatonin is a hormone made by the pineal gland of the brain. It is believed that melatonin helps our brains to know when it is time to sleep. Melatonin supplements in pill form can also be taken and may be made from natural or synthetic melatonin. As natural melatonin is made from animals, it may be contaminated with a virus and should be avoided.
Melatonin can be used to treat insomnia and to prevent jet lag. There is still little scientific evidence to prove its role in preventing disease or promoting health.
Melatonin is sold without a prescription in the United States. However, melatonin products are not approved by the U.S. Food and Drug Administration.
It may be better not to take melatonin until we know more about it. If you decide to try it, talk to your doctor first.
